If you were to go EFI, how would you do it? Why?

That is exactly right. Most standalone ECU's offer that feature. But the Holley packs the same features as the $$$$$ systems for a fraction of the cost.
Take a look at the features list. It's damn impressive.

Richard and crew do some great work. As I mentioned before. He was one of the few shops and fabricators that got to see the original pikes peak crash wreckage up close. Analyze it, and learn from that lesson on how to make cages better.

I really admire the posters that are good at and enjoy mapping fuel systems...it takes some time and experience to get good at it just like anything else.
BUT..The last two post are why I'd go with the LS3/GM stock set up....you need to "learn a new trade or hobby" to do it all. ...and you could really have some fun should anything go wrong a long way from the home base.
With a LS3/Stock gm system, just get it to any GM dealership...(which means a wrecker probably even then). Let them diagnose, get the parts, and fix it....while you get a room and go have a steak.

Hilborn converted to EFI.
WMF62 did a great job converting his old Rochester Fuel injection while maintaining the period correct look.
I ran this converted Hilborn stack injection on my 62 Corvette for a few years, with no problems that couldn't be corrected easily.
It it now on my 57 Corvette Gasser.
We built it without fuel rails and hid the majority of the electronics to maintain the "old school" look.
Fox Engineering did the machine work and specified the injectors and injectors, and the ECU is a Megasquirt with a Megasquirt relay board.
Total cost under $4000.00 with self tuning software.
I had no automotive computer experience when I started and I learned a lot.
A friend and I just finished a Crower 8 stack unit on a 66 Corvette Coupe. We used a FAST ecu and it works fine.

You didn't mention if you were going auto or manual trans. If you are going auto, I would buy an E-Rod LS3 with 4L65-E from GM. Pretty much complete and all brand new from GM. I would also buy an aftermarket stainless fuel tank set up for a late model internal fuel pump.

Good link..
It doesn't get much simplier than that to have the latest technology in a FI engine and OD transmission set up.

Surely there has to be someone who had a bad experience and converted back to carb, but I've never ever heard of one. I converted my 66 Skylark last year to LS and it totally transformed the car. I would do my vettes in an instant if they weren't so original.

I am interested in this and an LS3. I believe this kit is the most practical and with LS3 you wont need a return fuel line.....ECU is in / under the fuel rails...

Assuming a guy buys an LS3 from GM, does using the MSD controller void the warranty?

If you want a totally fresh start try a GM Ramjet 350 crate engine with FI . Complete setup from pan to ECU is around $5500.00.
Just add gas and 12 volts and away you go.
Did this in a 62 Corvette a few years ago, excellent performance and gas mileage.
I used a Rock Valley tank with in tank pump, beautiful tank, I hated to cover it up.

This tank or the one corvette central sells will make the tank conversion portion a lot easier.
I would post the link to Corvette Centrals tank, but their website is screwed up currently.

Charles (cbernhardt) has one in a '62 he built for his wife Carroll.
It's built around a stock frame modifield with a C4 suspension. He may be able to shed some light regarding the hood clearance. If it clears a C1 hood, I would guess that it would also clear a C2 hood??

When I installed the Ramjet engine in my 62 I had to get about 3/4 inch of hood clearance. I cut about 3/8" from the lower rubber engine mount rubber's and also cut about 5/8 inch out of the center hood brace and body worked it.
It worked out fine.

Can you tell I'm not a fan? When you put in a conversion that is within striking range of an entire crate motor swap out I'm not seeing the sense. Of course, if you just want to fiddle around with something new and have money I can see that. I did it with my Tremec 5- speed...

He snatched it off the engine and put the carb back on.

Well, the both guy that built my 427 SB motor AND the tuner said the motor would never be as well behaved as it is below 1500-2000 RPM if it didn't have EFI. I can cruise at 1200 RPM in top gear and it won't fall on its face if i open the throttle, if i feel the desire.

Probably because once you've shelled out $3K for a mod you feel compelled to see it through and damn the expense. So you fork over the extra $2K-$2.5K to do all the other things to make it work half-@ss.

I'm not debating that EFI may yield some benefits but the ROI is what I question...along with the somewhat sleazy, "....its so easy a caveman could do it" teaser ads.
How many here just bolted on the electronic F/I carb and fuel pump without a return line or ignition upgrade and are happy campers ??
